The connector-types response for MySQL connector type contains some nulls where presumably there should be connector property defns.  I've identified four properties in MySqlConnectorIntegrator that generate nulls:

 

SNAPSHOT_EVENTS_AS_INSERTS,

GTID_NEW_CHANNEL_POSITION,

BINARY_HANDLING_MODE,

ROW_COUNT_FOR_STREAMING_RESULT_SETS

 

Example section:

{ "category": "CONNECTOR", "defaultValue": true, "description": "MySQL allows user to insert year value as either 2-digit or 4-digit. In case of two digit the value is automatically mapped into 1970 - 2069.false - delegates the implicit conversion to the databasetrue - (the default) Debezium makes the conversion", "displayName": "Enable Time Adjuster", "isMandatory": false, "name": "enable.time.adjuster", "type": "BOOLEAN" }

,
null,

{ "category": "CONNECTOR", "defaultValue": true, "description": "If set to true, we will only produce DML events into Kafka for transactions that were written on mysql servers with UUIDs matching the filters defined by the gtid.source.includes or gtid.source.excludes configuration options, if they are specified.", "displayName": "Filter DML events", "isMandatory": false, "name": "gtid.source.filter.dml.events", "type": "BOOLEAN" }
